I agree with what you say. I think the rad is 26” high-22” wide. I know the car will go to the point of no return. I have no concerns over the rad, did a lot of research and I am confident it is right for the job. Slight rise in temp I can live with, but I know it would continue to climb to the point of no return if you didn’t give it a run. That is not something I will live with. I did learn from the feedback (what I suspected) is the fan is too deep into the shroud and the fix is ordered today, that is my first step.
